chessx
ChessX is a free, open-source chess database and PGN viewer for macOS, Linux and Windows. It lets users load and save PGN files, browse chess games with variations, enter moves and comments, set up custom board positions, search databases for text or positions, display move trees, and analyze games using UCI and Winboard/Xboard chess engines. The app includes an integrated Stockfish engine, supports FICS online play, integrates Nalimov and Syzygy tablebases, and offers a training mode for studying openings and opponents. It is widely used by chess players for database management, game analysis, opening preparation and online play.
AI Recommendation
1 suggestionChessX appears to be actively maintained as an open-source project, but we could not confirm from the available search results whether a native Apple Silicon build is currently available by default. The SourceForge project page is current and the app continues to receive updates. Given that Apple will remove Rosetta 2 support in macOS 28 (late 2027), you should contact the ChessX developers via the SourceForge project page or GitHub repository to ask whether a native Apple Silicon build is available now or planned before that deadline. If a native build is not yet available, ask whether one is under active development. In the meantime, the Intel build continues to run under Rosetta 2, giving you time to confirm the project's Apple Silicon status with the developers directly.
